FRICTIONAL GEARING FORNIOTORS.

SPECIFICATION forming part of' Letters Patent No. 773,615, datedNovember 1, 1904.

Application filed January 24, 1903. Serial No. 140,357. (No model.) l

To ctZZ whom it 71mg/ concern:

Beit known that I, EDWARD WV. VICKEY, a citizen of the United States ofAmerica, residing at East Chicago, in the county of Lake and State ofIndiana, have invented certain new and useful Improvements in FrictionalGearing for Motors, of which the following is a specification.

My invention relates to certain improvements in frictional gearingforlmotors, relating particularly to the means by which the motor isheld in position and the power transmitte'd therefrom to the desiredwork. j

The invention is designed especially with a view to the use of afriction-gear in the transmission of the power, and it is one of themainpurposes of the invention to provide means for neutralizing' the greatthrust upon the bearings which is incident to the ordinaryfriction-gearing.

`The invention is illustrated by means of a simple apparatus shown in'the drawings `presented herewith, and the characteristic fea-. tures ofimprovement wherein the invention lies are definitely pointed out in theclaims. In the drawings, Figure 1 is a plan view of said apparatus; Fig.2, a side elevation, and

Fig. 3 a detail transverse section in line 3 3 of Fig. l.

Referring to the drawings, A represents a stationary framework havingthe transverse portions a a and the longitudinal portions w3. Intheportions a2 Z3 are bearings Z o', in which is journaled a transverseshaft B,

Acarrying a motor of any suitable type, which is contained within thecasing C. The motor may be an electric motor, in which case the armaturewill be mounted directly on the shaft, or it may be any other type ofmotor, in which B will be the crank-shaft or drivingshaft, by means ofwhich the power is transmitted to the work. The particular style ofmotor being entirely immaterial, it is thought unnecessary to illustratethe same in detail.

On the opposite ends of the shaft B are friction-disks Z22 Z3, upon theouter faces of which run friction-pinions CZ CZ, feathered,respectively, upon shafts D D, so as to be movable longitudinallythereon. These shafts are journaled at one end in bearings Z2 Z3 in thetransverse part a of the frame and adjacent to the other end in bearingsCZ* d5, and propeller-screws E E are shown upon the ends of the shaftsto illustrate one very advantageous application of my invention. Thehubs of the pinions CZ CZ are cireumferentially grooved, as seen at Z6dl, and split ringsff' are provided in the grooves, secured to pivotpinsf2 f3, (see Fig. 3,) said pins being pivoted in forked levers F F',hinged at the bottom and having pivoted thereto at their topslongitudinally-extending rods G Gr', extending to hand-levers I-I H.

Suitable means for adjusting the frictional pressure of the pinions uponthe frict-ion-disks may be provided, the means here shown being simplyslotted bearings, as seen at Z2 (Z3. Any of the well-known means foradjusting the friction-disks may be employed for this purpose.

It will be seen that vin operation the pressure of the friction-pinionsis applied longitudinally of the driving-shaft B, and the pressure ofone pinion balances that of the other, so that no thrust-bearing isrequired to oppose this pressure.

By means of the handles H H/ either one of the friction-pinions may bemoved radially of its corresponding friction-disk to vary the speed,reverse the motion, or bring the corresponding longitudinal shaft torest, in the latter case the friction-pinion being upon the center ofthe disk, at which point the disk may have a slight depression toprevent the wearing of the pinions.

By the use of the two shafts upon opposite sides havingindependently-operated frictiongears the apparatus may be applied to thepropulsion of a boat, and the latter may be steered by means of thehandles H, one screw being run at a greater velocity than the other0r,if necessary, in the opposite direction from the other.

rfhere are numerous applications which it is thought unnecessary torefer to, and the invention in its main features is independent ofdetails of construction.

I claim as new and desire to secure by Letters Patenta 1. Thecombination with a driving-shaft and opposite frictional disksperpendicular thereto, of oppositely-disposed frictional pinionsperpendicular to and bearing upon said disks, whereby the pressure ofone pinion balances that of the other, andmeans for moving said pinionsradially upon the disks independently of each other and across thecenter of the frictional surfaces.

2. The combination with a pair of screwpropellers having parallelshafts, of a motor between said shafts having a driving-shaft extendingtherethrough transverse to the propeller-shafts, friction-disks upon theopposite ends of the driving-shaft, friction-pinions secured againstrotation upon the propeller- I5 shafts, and movable longitudinallythereof over the faces of the propeller-shafts and across the centersthereof, and lindependently of each other, substantially as described.

In witness whereof Iihave signed the above 2O application for LettersPatent, at Chicago, in the county of Cook and State of lllinois, this19th day of January, 1903.
